The first time Jose Mourinho took over as Chelsea manager, he was armed with unending money to spend on any player he wished for.
However, come the start of his second stint as Blues manager, matters have changed a little, with the Financial Fairplay rules preventing clubs from overspending - how effective it will be and whether it will prevent rich clubs from spending as much as they want is another matter of course.
Mourinho has already brought in Andre Schurrle from Bayer Leverkusen for around £20 million ($31 million), and has been linked with the likes of Edinson Cavani, Hulk and Wesley Sneijder to just name a few - all of whom will come at quite a price.
The Portuguese, though, is embracing the challenge of working within the FFP rules. "It's very motivational and demands more from you," he told the club's official website. "You have to think more about every decision and every move.
"Every wrong move you make has an influence on the future. You need to work more closely with the board in the financial area, you have to have a different perspective and a different look at the players on loan and youth football.
"It's more global. Instead of just focusing on your team, and your targets and ambitions, it's an overall view. It's a different profile of job and I'm happy with that, I'm enjoying that."
Mourinho believes he left a successful structure at the club when he left in 2007, which is in place even now and has served Chelsea really well over the years.
"I'm not worried about a definition of success, I'm worried about high quality work in every area I can influence," he said.
"That is the basis for success and a good definition of success. There was one Chelsea manager, Luiz Felipe Scolari, who when he came to Chelsea, he was saying he never saw a club with such organisation in the analysis department, he never saw a group of players with such a working ethic.
"That was a year after me and I was saying to myself and my assistants that he never mentioned my name, but it was a big compliment because it was my working ethic, my department of analysis and preparation.
"It was (match analyst) James Melbourne who came to me when he was a young kid and now he's the head of that department. That's my work, that's success."
According to Mourinho, stability is the key aspect that he wants to bring to Chelsea during his second spell, with Champions League qualification the bare minimum for every season.
"We need to go back to this stability," he added. "It's important for the players, for the young players' development, for the club, for the fan base and for the economic situation which is more important with Financial Fair Play.
"This is what we want, me as a manager, the owner and the board. The owner and the board want stability and then after that if we are working well and working together, success comes naturally.
"Everybody accepts the way we are going. I'm not trying to push in a different way. We are all in the same direction."
